The Amazing World of Lime Course

Everything you need to know about using lime: How to mix and apply it as a render, mortar, limecrete and paint.

  Enroll in Course

Lime is one of the most underused, useful and beautiful building materials out there. It's amazing stuff, and does nearly everything Portland cement does but better. Lime allows structures to breathe in a way Portland cement never can, significantly reducing the chances of damp in your building. It's softer and more malleable, and cures more slowly giving you time to work it beautifully before it sets. This softness is important in mortar work - especially in old buildings. Portland cement is too hard and non-porous, so it ultimately begins to 'eat away' at the stones. It's been banned by the English Heritage society for this very reason. Lime is a fungicide and an insecticide, and in many places very inexpensive. Unless you're building a multistory car park, lime is the way.

Still doubting? Scroll down to the curriculum and watch the video tour of my lime-filled kitchen.

So What Can You Actually Do With Lime?

Lime is extremely versatile. There's a lot you can create. You can use it as render:


Or as a mortar:


Or as a 'crete:

You can make lime paint:


You can grout flagstones or tiles with it:


Or make floors:

Environmental Benefits

Lime generates roughly 25% of the carbon that Portland cement does in production,and then slowly reabsorbs that carbon as it cures. Seeing as Portland cement is currently the second largest emitter of CO2 into the atmosphere after fossil fuels, we could do with using a lot more lime and a lot less Portland.

If you want to learn how to use lime in a host of different ways, the All About Lime Course will show you the way.

Atulya K Bingham

Hi! I'm Atulya. My love of natural building arose from nowhere. Back in 2011 I was living in a field in Turkey. Bit by bit, out of necessity I taught myself to build with mud. It became a creative passion. Within a year I had constructed a house. I have been mud building and writing about it ever since.

Today I am founder and author of The Mud Home natural building site. I also write about natural building for publications such as Mother Earth News and the Owner Builder Magazine.
